Facultative air-breathing in the genus (Ref. 126274); Inhabits swamps, quiet pools and backwaters, either in open, shallow stretches or the vegetated margins of these areas. Found around the shelter of rocks and vegetation on the bottom, also in streams draining into lakes (Ref. 44894). Believed to spawn in winter or spring following rains. Sexual maturity is reached after one year for males and two years for females. Fecundity is typically low; spawning females lay between 70-500 eggs in well-sheltered sites (underneath rocks). The eggs require around 50-60 days to hatch (Ref. 44894). Feeds on aquatic insects and their larvae, also small invertebrates (Ref. 44894).
在开放又水浅的支流或这些区域的长满植物边缘中也栖息于沼泽，静止的池水与洄水区。 发现于在底部上的岩石的庇护所与植物周围了, 也在溪流中进入湖之内注入.(参考文献 44894) 相信冬天时产卵，否则春天跟随雨。 性成熟在一年之后被达成雄鱼与母鱼二年。 孕卵数典型低; 产卵雌性在隐匿良好的位置中在 70-500个卵之间生下。 (在岩石的下面) 卵需要大约 50-60 天孵化。 (参考文献 44894) 吃水生昆虫与他们的幼体, 也小型无脊椎动物.(参考文献 44894)
